What, if anything, did Russell know? Will she be charged in connection with the attacks? And how is she spending her days? Team 5 Investigates Kathy Curran tracked her down to find out, after she and her attorneys declined multiple requests for interviews.

Team 5 caught up with Katherine Russell the day after her brother-in-law Dzhokhar Tsarnaev was hit with a 30-count indictment, including a charge of using a weapon of mass destruction resulting in death. Russell headed out for the day with her sister and 3-year-old daughter.

Team 5 saw her leave her parents’ home in North Kingstown, R.I., drop her sister off at work, stop for gas, hit the drive through at Dunkin Donuts and then grab a coffee at Starbucks. Russell then headed to a home in Warwick.

Her husband, Tamerlan, was the alleged mastermind behind the plot to bomb the marathon and the violent rampage that followed. Four people were killed, almost 200 injured.

Russell has been cooperating with federal investigators who are trying to figure out whether she played any role in the attack or the tragedy that followed. Sources said her brother-in-law told investigators she was not involved.

Curran tried to speak with Russell but she declined to answer any questions.

“Did you see a change in him (Tamerlan) after he went to Russia?” asked Curran. “Did you know he was building bombs?” “What do you want to say to the victims and their families?”

Defense attorney Kevin Reddington, who represents Catherine Greig, the woman closest to mobster Whitey Bulger, told Team 5, “I tend to think she’s just a person that was hard-working and never there and probably in a controlling environment and was not aware of anything that was going on.”

We received no answers from Russell. The 24-year-old converted to Islam and married Tsarnaev in 2010. The couple lived together in a small Cambridge apartment on Norfolk Street where according to prosecutors, electronic parts for the bombs were shipped and where sources said the bombs were built.

The indictment also alleges the brothers stocked up on explosives and practiced shooting guns at a firing range in Manchester, N.H.

“You didn’t know he was ordering parts online or target practice in New Hampshire?” asked Curran. "Katherine, you have a child, your husband is accused of killing a child and other innocent people, you don't want to say anything to us?"

Russell walked away from Team 5 without providing answers.

Reddington said prosecutors may be looking at whether or not Russell saw the Tsarnaev brothers’ pictures when they were released by the FBI and tipped them off, whether or not she was aware of the plot or if she provided any type of support, "which I do not see at all from what I understand is available out there now,” said Reddington.

A spokesperson for the U.S. Attorney’s Office told Team 5 the investigation is still active and ongoing. Russell’s lawyers declined our repeated requests for comment but thanked us for our interest in Katherine Russell.
